Eating common canned foods is exposing consumers to levels of bisphenol A (BPA) equal to levels shown to cause health problems in laboratory animals, according to a new study released today by The National Work Group for Safe Markets, a coalition of public health and environmental health groups. The study, No Silver Lining, tested food from 50 cans from 19 US states and one Canadian province for BPA contamination. Over 90% of the cans tested had detectable levels of BPA, some at higher levels than have been detected in previous studies.

The canned foods tested were brand name fish, fruits, vegetables, beans, soups, tomato products, sodas, and milks, which together represent “real-life” meal options for a wide range of North American consumers. The cans were purchased from retail stores and were chosen from report participants’ pantry shelves, and sent to an independent laboratory for testing. One can of DelMonte green beans had the highest levels of BPA ever found in canned food, at 1,140 parts per billion.
